WSO2 ESB team released the latest benchmark ESB Performance Round 7.5the result tests are based on the previous serious of performance test carried by different vendors.The main idea of this article is to provide the facts that WSO2 ESB still holding the position as the fastest message mediation engine with with minimum latency.
   The test cases were executed by categorizing the sections, such as Passthough Invocation, Content Base Routing (CBR),Content Header Base Routing (CHBR), and Security scenarios.
    The test cases were designed to measure the throughput (TPS) under different concurrences with different size of messages and to get more visualization aspect, we did a summery graph and out of different vendors such as Ultra ESB,Teland ESB, It was clearly visualize that WSO2 outcomes others by considerable margin when the average calculated.
    And also when considering the individual scenarios; WSO2 ESB performed well without seen any exception or any payload corruptions and to verify this further more; WSO2 team run corruption checker and also used Jmeter response assertion to make sure there won't be any corruption under different high concurrences.
   Nevertheless Surprisingly, we did observe improvements of Mule ESB, which we have noted that it performs well over Ultra ESB for some use cases such as CBR, CHBR

   Anyway, the main fact that this article trying to bid, the claims made by some vendors by arguing the default pack which does the payload corruption,but yes we did identified such claim but, never with the default setting , it was with the StreamXpath where this was due to a very negligible error which we have fixed in no time.

Why we did ESB Performance round 7.5 ? 
  The main reason why WSO2 did this because as professional,we need to make sure that WSO2 ESB is the strongest and the well performed ESB available in the market and we need to make sure that we did answer the questions raised by ESB PERFORMANCE ROUND 7. 
     When considering the OPEN source nature I think WSO2 ESB is the only ESB that has much features that allow different users to
try them freely and the source is open and they could see anything, and WSO2 welcomes the open community ideas, and again WSO2 ESB do not have any sort of hidden code which not sharable or available under different license.

Finally, I know this would hurt few guys/organizations because they put such effort by spending days and nights to QA other vendors products and written article by highlighting issues/errors which they found as disaster, I Know we will see a Performance Round 8, sooner rather than later because the guys who claims to be the champions now are in at 3rd place so they need to bring their act to gather and need response faster, I think they should now need to plan different execution scenarios for the next round such as JSON, JSON Path evaluation, and we know RESTful invocations are now becoming the huge topic and people waiting to see ESB's performance in JSON related usecases.But the bottom-line is still WSO2 ESB will hold the leading position.. bet my word...!  Enjoy...

The WSO2 Enterprise Service Bus (ESB) 4.8.1 Released!

WSO2 ESB team is pleased to announce the release of version 4.8.1 of the Open Source Enterprise Service Bus (ESB).
WSO2 ESB is a fast, lightweight and user friendly open source Enterprise Service Bus (ESB) distributed under the Apache Software License v2.0. WSO2 ESB allows system administrators and developers to easily configure message routing, intermediation, transformation, logging, task scheduling, fail over routing and load balancing. It also supports transport switching, eventing, rule based mediation and priority based mediation for advanced integration requirements. The ESB runtime is designed to be completely asynchronous, non-blocking and streaming based on the Apache Synapse mediation engine.
WSO2 ESB 4.8.1 is developed on top of the revolutionary WSO2 Carbon platform (Middleware a' la carte), an OSGi based framework that provides seamless modularity to your SOA via componentization. This release also contains many new features and a range of optional components (add-ons) that can be installed to customize the behavior of the ESB. Further, any existing features of the ESB which are not required to your environment can be easily removed using the underlying provisioning framework of Carbon. In brief, WSO2 ESB can be fully customized and tailored to meet your exact SOA needs.
You can download this distribution from http://wso2.com/products/enterprise-service-bus/ and give it a try.

How to Run

  1. Extract the downloaded zip
  2. Go to the bin directory in the extracted folder
  3. Run the wso2server.sh or wso2server.bat as appropriate
  4. Point your browser to the URL https://localhost:9443/carbon
  5. Use "admin", "admin" as the username and password to login as an admin
  6. If you need to start the OSGi console with the server use the property -DosgiConsole when starting the server. The INSTALL.txt file found on the installation directory will give you a comprehensive set of options and properties that can be passed into the startup script
  7. Sample configurations can be started by the wso2esb-samples script passing the sample number with the -sn option (Please have a look at the samples guide for more information, on running samples)

Enhancements in WSO2 ESB 4.8.1

  • HL7 Message Store Implementation with Console for message audit and replay
  • Thread Pooled HL7 Server Endpoints
  • Improvements for working with Invalid HL7 Messages
  • Enhancing FAST XSLT Mediator.
  • cApp deployment enhacements and stabilizing class mediator hot deployment.

Key Features of WSO2 ESB

  • Proxy services - facilitating synchronous/asynchronous transport, interface (WSDL/Schema/Policy), message format (SOAP 1.1/1.2, POX/REST, Text, Binary), QoS (WS-Addressing/WS-Security) and optimization switching (MTOM/SwA).
  • API facilitating building REST APIs
  • Non-blocking HTTP/S transports based on Apache HttpCore-NIO for ultra-fast execution and support for thousands of connections at high concurrency with constant memory usage.
  • Built in Registry/Repository, facilitating dynamic updating and reloading of the configuration and associated resources (e.g. XSLTs, XSD, WSDL, Policies, JS configurations ..)
  • Easily extendable via custom Java classes (mediator and command)/Spring configurations, or BSF Scripting languages (Javascript, Ruby, Groovy, etc.)
  • Built in support for scheduling tasks using the Quartz scheduler.
  • Load-balancing (with or without sticky sessions)/Fail-over, and clustered Throttling and Caching support

  • Lightweight, XML and Web services centric messaging model
  • Support for industrial standards (Hessian binary web service protocol/ Financial Information eXchange protocol and optional Health Level-7 protocol)
  • Enhanced support for the VFS (File/FTP/SFTP), JMS, Mail transports with optional TCP/UDP transports and transport switching among any of the above transports
  • Support for message splitting & aggregation using the EIP and service callouts
  • Database lookup & store support with DBMediators with reusable database connection pools
  • WS-Eventing support
  • Rule based mediation of the messages using the Drools rule engine
  • Transactions support via the JMS transport and Transaction mediator for database mediators
  • Internationalized GUI management console with user management for configuration development
  • Integrated monitoring support with statistics, configurable logging and tracing
